8 Claims. (Cl. '189-75) and overlaps the wall sheathing, and with means for scour-- ing such a strip to the metal frame.

In carrying out my invention in a preferred form, I

employ a metal window frame having a peripheral flange projecting therefrom in the plane of the outer face of the frame. The nailing strip, which is of uniform sec- -tion throughout its length has a first flange engageable with the inner face of the frame ilange and a second ange, or nailing n, which lies parallel to but offset outwardly from the iirst flange. The intermediate portion of' the strip, through which the two flanges are united provides a shoulder which, when the strip is applied to the frame, seats against the edge of the frame-hange. YThe strip may additionally embody a third ange projecting perpendicularly to the other flanges and adapted to form a caulking stop. Means, which may take various forms, is provided for securing the strip to the frame in such a position that the nailing iin will project from the frame to overlap and be nailed to the wall framing at the sides of the window. Preferably a single length ofthe strip will be bent intermediate its length to extend along two or more sides of the window frame. Y

`Other objects and features of theV invention will become apparent as the detailed description of a preferred embodiment thereof proceeds.

The accompanying drawing illustrates the invention. In such drawing:

Fig. 2 is a fragmental view similar to Fig. 1 but showing on an enlarged scale that portion of the strip which will be positioned -at a corner of the window frame, the full lines showing the strip in an original condition, and the dotted lines showing the strip bent to provide a corner portion of the complete strip shown in Fig. l;

Fig. 3 is a vertical section througha window, showing one means for securing the nailing strip in place on the window frame, with the nailing strip and frame secured to the house framing;

Fig. 4 is a view similar to Fig. 3, but showing a modied form of means for securing the nailing strip to the window frame; and

Fig. 5 is an isometric view of a length of a wedging element constituting the strip-securing means shown in Fig. 3.

As shown, the house framing, including sheathing is formed from lumber `to provide a framed opening 12 slightly larger than the outside dimensions of the metal window frame 14 to be installed therein. In accordance with customary practice in carpentry, the framed opening 12 need be and here is only roughly corresponding in size and shape to the window frame to be installed.

lIn accordance with my invention, I provide a metal nailing-strip member, as indicated generally by the numeral 20, for securing the window frame 14 to the house framing. As shown in section in Figs. 3 and 4, the nailing-strip desirably comprises a flange or nailing iin 22 adapted to lie against the front face of the sheathing 10. Such nailing fin may be provided at intervals with openings 23 for the passage of the nails 23' by which the strip is secured to the sheathing or, alternatively the strip may be made of metal soft enough land the n 22 thin enough to require no such holes. IOffset but parallel to the in 22 is a flange 30 united to the iin 22 through a web 31 which lies in a plane perpendicular to the iin 22 and flange 30. The strip 20 may also include a caulking stop 24 which projects perpendicularly from the tin 22,

Y conveniently in the plane of the web 31.

` the meeting surface of the key-flange are shaped to con-v fIn the embodiment shown in Fig. 3, the window frame 14 is provided in the plane of its front face with a peripheral ange 32 and, spaced inwardly of the wall from such flange; with a second ange 34. When applied to such a window frame, the flange 30 of the strip 20 lies against the inner face of the frame iiange 32 with the web 31 of the strip seated against the edge of the flange. To hold the strip in such position I may employ keys 38 (Fig. 5)`adapted to be forced between the anges 30 and 34 in the manner shown in Fig. 3. Each key38 comprises a length of metal stock of a general T-shape, the web 39 of which is adapted to be'frorced between the stripflange 30 and the frame-flange 34, as shown in Fig. 3. To accommodate for dimensional variations, the frameflanges 32 and 34 are spaced far enough apart to enable the web 39 of the key to be of relatively great thickness and such web is provided along its free edge with a slit or groove 39 which leaves the web portions on each side of it still ofrsubstantial thickness and strength. That side of the web 39 which engages the strip-flange 30, and

form respectively to the strip-ange 30 and strip-web 31, but the opposite side of the key-web is relieved at its junction with the ange, as indicated at 40 in Fig. 5, to insure that the wedging eiort created when the key is linally positioned will vbe centered well within the limits of the area of contact between the strip-ange 30 andv frame-flange 32.

The keys 38 may be relatively short, and several may be used at spaced intervals along each side of the window. After a nailing strip has been applied to the window frame, each key is forced into the space between the flanges 30 and 34 until the key-flange engages the web 31 of the nailing strip and forces it against the edge of the frame-flange 30. To retain each key in its strip-clamping position, the free edge of the flange 34 may be bent over it, as indicated at 41 in Fig. 3.

In the modified arrangement shown in Fig. 4, the frame-flange 34 is eliminated, but the flange 32 is retained; and the nailing strip is secured thereto by clips 46 conveniently of sheet-metal formed into a shallow channel section to provide an outer lip which overlies the strip-web 31 and an inner lip which engages the inner face of the frame-flange 32. Closely adjacent the latter lip, the clip is provided with one or more holes 47 which receive the threaded ends 'of screws 50 passing through openings 48 in the flange 32. Desirably, the screws 50 are tapered and of the self-typing variety and the holes 47 are located so close to the inner lip that as the screws are tightened they crowd the clip inwardly in the plane of window to draw the web 31 of the nailing strip tightly against the outer edge of the framediange 32 while, at the same type, clamping the strip-ange 30 against the inner face of the frame-tiange 32.

As shown in Fig. 1, the complete nailing strip 20 for a window is desirably formed from two sections, each bent into a general U-shape from straight lengths f stock. At the location of each bend in the strip, the flange 30 is notched as at 52 (Fig. 2) and the nailing lin 22 is slit as at54, thus leaving only the caulking' stop 24 to be bent. Where the ends of the two U-shapedsections abut at each side of the window frame', the joint between them is desirably concealed' as by a sheet-metal. clip 56 havingr opposed walls 58, which grip the abutting ends of the caulkng stop 24, and an extension 58', which overlies the nailing iin so that it may be pierced by one of the nails 23.

After the nailing strip Z0 has been secured to the window frame the latter is positioned inthe Wall opening with the nailing n 32 projecting outwardly from the' frame to overlap the sheathing and the nails 23 are driven to secure the' window firmly in place with the caulking stop 24'projecting'forwardly from the sheathing. When the desired facing 26l is later 'applied to the wall, space is left between it and the stop 24 for the reception of caulking 59.
